Respuesta :
we have
[tex]j(x) =x^{2}-9\\k(x)=-x+7[/tex]
we know that
[tex]j(x)+k(x)[/tex] --------> results in a second degree polynomial
[tex]j(x)-k(x)[/tex] --------> results in a second degree polynomial
[tex]j(x)*k(x)[/tex] --------> results in a third degree polynomial
[tex]j(x)/k(x)[/tex] --------> results in a first degree polynomial
so
[tex]j(x)*k(x)[/tex]
[tex](x^{2}-9)*(-x+7)=-x^{3} +7x^{2} +9x-63[/tex]
therefore
the answer is
the multiplication of j(x) and k(x)
Answer:
No operations...... the other answer is wrong trust me
